In compliance with Good Laboratory Practise (GLP) according to CFR 21 part 11 experiments should be signed and locked after completion. 

By default, eLABJournal is configured to require a single digital signature to sign experiments, but it is possible to require a witness to counter-sign experiments prior to permanently locking experiments. Note that signed experiments are locked for data modification afterwards, but they can be opened in a view-only mode. To sign an experiment, open the experiment and click on the sign button.

Enter your credentials and click on Sign Experiment. Note that you can also sign your experiments with the two-step verification code generated. 

Signed experiments are locked into a read-only mode and the digital signature including time stamp is visible in the experiment header.

Signing Experiments with two-factor code

If your organisation uses an organisation-specific login (i.e LDAP / AD / SSO), passwords are not stored within the eLABJournal system. For that reason experiments can only be signed using a generated two-step verification code. To sign experiments with a generated two-step verification code, you first need to set up two-step verification for your account.

After clicking on the sign icon, you can enter the two-step verification code in the appeared window.

Open the eLabJournal app on your phone and go to Two-Step Verification code.

Enter the 6 digits and click Sign Experiment.
